[gtk+] Add an expander reftest

[Matthias Clasen <matthiasc src gnome org>]

commit 5bebbb06fa56b83a2bc5309a53ecc32737f36045
Author: Matthias Clasen <mclasen redhat com>
Date:   Mon Jun 2 22:33:20 2014 -0400

    Add an expander reftest
    
    This test check that resizing the window when expanding
    the expander yields the same end result as having the
    expander expanded to begin with. The test uses the inhibit
    mechanism introduced in the previous commit.
